MELVIN STRINGER, OF NEW. YORK, N. Y.

BAND BRAKE.

Application filed Octolier 19, 1925. Serial No. 63,234.

My invention relates to improvements in band brakes, and moreparticularly has ref 'erence to and is illustrated in the accompanyingdrawings in its application to a split band brake, which may be aninternal band, such as are commonly used in automobiles and is inthenature of a modification of my co-pending applicatiOn S. N. 734,935.

According to a preferred embodiment of my invention, the brake isoperated at the I split or opening in the band insuch a man- ,ner thatthe trailing side or end of the band is advanced over the opposing sidein applying the brake, so as to apply the band more uniformly to thedrum throughout its length, thereby increasing its efficiency andbraking power.

ltn the accompanying drawings, I have illustrated in lFig. 1 inperspective a suitable form ofband brake embodying an application of myinvention. Fig. 2 is a similar view illustrating a modification. Fig. 3is a broken section illustrating the arrangement of the separatingstrips.

1 indicates a steel band which is split or separated at the ends asindicated at 2 and which is provided with a suitable bearing or support3. I

-ln Fig. 2 a two-part reinforcing web 4 and 5 is shown and may be used,the same preferably being secured to the band by cates a spring acrossthe split of the band.

8and9 indicate links pivotally mounted as shown in the toggle 10, saidtoggle being suitably secured to the usual pin 11 for rotating the same.

The link and toggle pins 12, 13 are usually mounted equally distant fromthe center of rotation of the toggle 10, but according to the preferredembodiment of any invention, and assuming that the vehicle is travelingfrom left to right, looking at the drawing, the pin or bearing 12 is ata slightly greater distance from the center 11 than the pin or bearing13. This causes the end of the band pointing in the direction ofrotation of the Inplace of the toggle, other means may be employed foropening theband, such for instance as the cam 10 shown in Fig. 2 and insuch case the adjacent ends of the band may be turned in and backed bythe webs 4 and!) as shown. Also in the modification shown in Fig. 2, theends of the spring 7 may be secured in the reinforcing webs as showninstead of to the link bearings 14, 15 shown in Fig. 1..

Referring more particularly to Fig. 3, it will be seen that theseparating strips 6 are spot welded to the inside of the band 1, and tothe periphery of the reinforcing piece 4, as shown at 16, 17, leaving aspace between said pieces and said band.

of course it will be understood that various modifications may be madein the construction and arrangement of parts without departing from thespirit of the invention as claimed.

I claim 1. In a band brake of the class described, a substantially fiatsteel band, and substantially fiat steel reinforcing webs substantiallyat right angles thereto and at the center of one side thereof, said websseparated from said band providing a space therebe tween.

2. In a hand brake of the class described, a substantially flat steelband, and substantially flat steel reinforcing webs substantially atright angles thereto and at the center of one side thereof, said websseparated from said band providing a space therebetween and said webssecured to said band.

3. In a band brake of the class described, a substantially flat steelband, and a twopart substantially flat steel'reinforring websubstantially at right angles thereto, said band turned in at the endsthereof and said web abutting said turned-in ends and sepaa ratingpieces between said web and said band.- 7 1 4. In a band brake of theclass described, 5 a substantially fiat steel band, and a substantiallyfiat two-part steel reinforcing web substantially at right anglesthereto, said band turned in at the ends thereof and two of the ends ofsaid web abutting said turnedin ends and a spring adjacent the ends of10 said band and anchored to said webs and separating pieces betweensaid web and said band.

In testimony whereof I hereunto aflix my signature.

MELVIN STRIN GER.
